It is a beautiful house and is a very good choice for vintage lovers. The decorations are really beautiful and we met 2 lovely dogs and 2 lovely cats there. The hosts are friendly and will give good recommendations about things to do in BKK. They said they would build a farm right opposite the house, hope we could have the chance to see that sometime in the future :)
p.s. I stayed at Mustang Nero during my Bangkok trip in 2015 and chose J No.14 in 2016. They have similar styles and both worth visiting.
